In the past, various brush-type applicators have been provided forapplying various types of pigments, lacquers, paints, correction fluidand the like.

These brush-type applicators employ brushes which extend into theliquid. Usually the liquid is relatively quick drying when exposed toair and substantial quantities of the liquid gather on the shank of theapplicator and on the brush so that not only is there the possibility ofliquid dripping in an undesirable manner, but too much liquid is usuallyleft on the brush for careful application, and substantial quantities ofthe liquid are wasted by drying on the shank of the brush.

The concept of this invention is to employ a fitting which is insertedin the neck of the container and wipingly engages both the tapered shankof the brush and the bristles to wipe all of the liquid from the shankand excess fluid from the bristles so that an accurate marking forobliterating errors can be obtained through the use of this device.

Still further objects and features of this invention reside in theprovision of a dripless brush applicator which is simple inconstruction, which is capable of being used with various existingformulations of correction liquid, and like lacquers, yet which issimple in construction and manufacture and inexpensive to produce so asto permit wide use and distribution.

These, together with the various ancillary objects and features of thisinvention, which will become apparent as the following descriptionproceeds, are attained by this dripless brush applicator, a preferredembodiment of which is illustrated in the accompanying drawing, by wayof example only, wherein:

FIG. 1 is an exploded sectional view of the dripless brush applicatorconstructed in accordance with the concepts of the present invention;

FIG. 2 is a bottom plan view of the fitting looking in the direction ofline 2-2 in FIG. 1;

FIG. 3 is a vertical sectional ,view of the invention shown in anassembled condition; and,

FIG. 4 is a view similar to FIG. 3, but showing the manner of operationof the device as the cap is being removed.

With continuing reference to the accompanying drawing, wherein likereference numerals designate similar parts throughout the various views,reference numeral 10 generally designates a container formed of glass orthe like having a neck 12 provided with external threads 14 thereon. Thecontainer 10 is preferably formed with a firm base and is adapted to befilled with a correction liquid 16 or similar lacquer which isrelatively quick drying. The neck 14 terminates in a mouth 18 forming ashoulder 20.

A fitting, generally indicated at 22, is provided and includes acylindrical portion 24 having a downwardly and inwardly taperingtruncated conical portion 26 integral therewith. Also integral with thecylindrical portion at the top thereof is a peripheral flange 28 whichis adapted to engage the shoulder 20 when the fitting 22 is force fittedin the neck. The cylindrical portion 24 clampingly engages the inside ofthe neck 12. The conical portion 26 has four annularly spaced slits 30therein which extend su tantially or a little more than half way theheight 0 the truncated conical portion 26 so that when in engagementwith said shank the uppermost portion of the conical portion is forcedagainst the neck.

A cap, generally indicated at 34, is provided which includes acylindrical portion 36 having internal threads 38 adapted to readilyengage the threads 14 and a top portion 40 having a dependentcylindrical .portion 42 extending downwardly therefrom. The cap 34further includes a shank 44 integral with or detachably secured to thecylindrical portion 42. The shank 44 is downwardly and inwardly tapered.Aflixed to the lower end 46 of the shank 44 are a plurality of bristles48 forming a brush.

After the fitting 22 has been force fitted in the neck 12, the cap isinserted through the fitting 22 and threaded on the neck 12. The shank44 and the bristles 48 extend into the fluid 16. When it is desired towithdraw the brush from the container, it is merely necessary to unscrewthe cap and lift the cap. The inner diameter of the tapered conicalportion is of less diameter than the smallest diameter of the shank 44and the bristles 48 so that it will wipe the shank 44 entirely cleanfrom liquid, while removing excess fluid from the bristles so that thebrush will be in a position for effective operation and use such asmarking out typewritten characters and the like.

A latitude of modification, substitution and change is intended in theforegoing disclosure, and in some instances, some features of thisinvention may be employed without a corresponding use of other features.

We claim:

1. An applicator comprising a fluid container having a neck providedwith external threads and provided with a mouth forming a shoulder, afitting disposed in said neck, said fitting including a cylindricalportion force fitted in said neck and a downwardly and inwardlyextending resilient truncated conical portion, a cap threadedlyremovable disposed on said neck, a downwardly and inwardly tapered shankdepending from said cap and extending through said fitting, bristles onthe lower end of said shank forming a brush, said conical portion havinga circular opening of less internal diameter than the smallest diameterof said shank and being engageable with said bristles to wipe said shankclean of fluid while removing excess material from said brush when saidcap is moved from said container, said conical portion having fourannularly equally spaced slits therein forming a plurality of wiperblades, said slits extending substantially only half the height of saidconical portion so that when said wiper blades are in engagement withsaid shank the uppermost part of said conical portion is additionallyforced against said neck to further clampingly hold said fitting in saidneck.
